    摘要： A system and method of providing quality of service (QoS)-enabled digital content in peer-to-peer (P2P) networks are provided. The QoS-enabled service system on the P2P network includes: a service provider capable of providing digital content; one or more user nodes receiving digital content from the service provider; one or more donor nodes lending resources for providing digital content; and a supernode receiving information on user nodes and donor nodes, and a copy of digital content from the service provider, allowing the exchange of digital content among the user nodes through P2P networking, and when at least one user node experiences a P2P networking error during the exchange of the digital content, arranging for a predetermined number of donor nodes from among the one or more donor nodes to join the P2P networking. According to the system and method, even when the function of a peer does not normally work on a P2P network, a donor as a replacement of the peer is utilized, thereby providing QoS-enabled digital content to a user requesting the digital content.

    摘要： Provided are a method and apparatus for relaying streaming data between peers including a first device and a second device in a peer-to-peer (P2P) overlay network. A method of relaying streaming data from the first device to the second device includes determining whether requested streaming data is streaming data that the first device is currently receiving when the first device is requested by the second device to relay streaming data to the second device. Then, the first device assigns a reception bandwidth for receiving the requested streaming data from a source device according to the determination result and receives the requested streaming data using the assigned reception bandwidth to relay the requested streaming data to the second device. Therefore, peers can receive streaming data at a high rate in a P2P network.
